Histogram for all four morphological types showing the position of P3/P0_max. Top: regular (black dashed line) and intermediate (red filled histogram) clusters are shown. There is a clear excess in the 0.3 r₅₀₀ aperture. Bottom: complex (black dashed line) and double (red filled histogram) clusters are displayed. The distribution is homogeneous since the position of the peak depends on the location of the second component or structure.
